Kiln

Kiln is a Refinement Building, which serves the purpose of refining Coal into Refined Carbon and Clay into Ceramic.

Recipes
Both recipes output with a temperature of 80 °C.

Heat economy
Kiln can be run as net heat negative, due to the lower mass of outputs. It requires feeding it a fuel above a certain temperature:


 * For refined carbon; HTC output/input ratio is 0.8 and threshold temperature of coal is around 9.60+ °C
 * With coal at 80 °C, heat consumption will be at 20%, destroying 6248.41 kDTU.
 * For ceramic; HTC output/input ratio is 0.77 and threshold temperature of both inputs is around -2.68+ °C
 * With both inputs at 80 °C, heat consumption will be at 23%, destroying 9073.61 kDTU.

The Kiln is unique as it does not have an Overheat Temperature and only exchanges heat with its surrounding gas, not with the tiles it stands on, its contents, the wire connecting it or the Duplicant delivering materials to it. As such, if placed in vacuum, it can be used to achieve high temperatures without using rocket exhaust gases or late-game materials, for example to create Refined Carbon, Ceramic, Petroleum or Glass at a higher efficiency.

Tips

 * It can be fully automated with Auto-Sweeper.
 * Kiln has no overheat temperature.

Trivia

 * Kiln's sprite resembles the traditional Scottish instrument: the bagpipes.
